What does Deathalicious mean the ink color costs you more?? Was he being sarcastic? You don't color these by HAND do you? Coloring by computer is SOOOOO much easier.Actually, as any freshmen CS major will tell you, adding color adds an order greater difficulty in each pixel representation. Now, pixels are manufactured in the back of your monitor, and the manufacture of black and white pixels is very inexpensive -- in fact, the cost for creating a black pixel actually cancels out the cost for creating a white pixel. It is for this reason that the early Macintoshes used a gray background composed of a 1-pixel checkerboard of black and white pixels -- it had the net effect of costing no energy from the pixel generator in the rear of the monitor, which kept the Macs cool and prevented them from needing a powerful fan to keep cool.
Colored pixels, however, take anywhere from 4 to 16 times as much energy to generate than a white pixel, depending on hue, saturation, and brightness. Larger monitors have a larger energy source, but also have to shoot their pixels a farther distance to the screen. However, the ratio of energy source to distance is such that it is still always better, energy wise, to use a larger monitor, which is why most graphic designers aren't content with a monitor smaller than 17 inches.
These costs are generally minimal when you are merely surfing the web, but astronomical when using a pixel-cruncher like Photoshop (or a similar painting program), which for the purposes of graphic design loops through its pixel creation much more quickly to provide a "realtime" editing environment. Microsoft Paint is, of course, not affected.
The drains on the pixel generator with extended color Photoshopping and image editing means that monitors wear out 50% quicker, which is why you see most graphic designers needing to get newer and bigger monitors every two years or so, while most programmers stick with the same 15 inch monitor for years.
